Ian Skerrett is probably best known for his role at the Eclipse Foundation as vice president of marketing, but for the past two-plus years he's also been leading the Eclipse effort to foster an open-source community around the Internet of Things (IoT).
"If you look at the Internet today, it's run on open source," Skerrett told me. "Linux, Apache and open standards like HTTP are the building blocks. If we're really going to get an Internet of Things, we need a set of core building blocks that anyone can use to develop commercial or internal solutions."
Eclipse IoT now includes 15 projects collectively aiming to reduce the complexity of developing IoT/M2M solutions. Most of the Eclipse literature on this initiative uses that "IoT/M2M" label, because machine-to-machine communication is where it all started, and because it continues to be an essential part of IoT. But is IoT more all encompassing, which, Skerrett says, is what makes developing IoT solutions so challenging.
"To put together an IoT solution today, you need people who understand gateways and networks, but also enterprise systems, data analytics, integration with ERP or CRM systems," he said. "There's some daunting complexity here, but we know that when you create frameworks and abstraction levels in software, it becomes much easier to put together these types of solutions."
The mission of the Eclipse IoT initiative is to establish an open IoT/M2M platform that comprises a set of services and frameworks, open-source implementations of standard protocols, and an Eclipse-based IDE for simplifying IoT/M2M development. The current list of projects likely to become part of that platform includes the Paho Project, which provides scalable open-source client implementations of open and standard messaging protocols for IoT/M2M apps. That list also includes several frameworks: Kura, which is a set of Java and OSGi services commonly required for IoT gateways (I/O services, data services, cloud services, networking, etc.); Mihini, which is an open-source framework written in the Lua scripting language; OM2M, an open-source implementation of the ETSI M2M standard; and the Wakaama Project, which will provide a C portable framework for building LWM2M clients and/or servers.
There's also SmartHome (named by Captain Obvious), which is a framework for building smart home solutions; Eclipse SCADA, which the Foundation describes as "a way to connect different industrial devices to a common communication system and post-process, as well as visualize the data to operating personnel;" and the Sandbox LWM2M Server, which provides a Web UI and a REST API to enable interaction with the registered clients. Koneki is an M2M developer tools project that's using Lua as its primarily programming language.
Eclipse IoT's protocol efforts are focused on providing open-source implementations of Message Queuing Telemetry Transport (MQTT), which is designed to connect "physical world devices" and networks with applications and middleware; CoAP (Constrained Application Protocol), which is a protocol specialized for use with constrained nodes and networks; and OMA LightweightM2M (LWM2M), which is an industry standard for device management of M2M/IoT devices.
A complete list of Eclipse IoT projects is available on the Foundation Web site here.
Even better, Skerrett will give attendees of our upcoming App Dev Trends 2014 Conference in December an in-depth look at the Eclipse IoT initiative and discuss the and the role of open source in the evolution of the Internet of Things.

There's a difference between a bug and a flaw, and an impressive group of software security mavens thinks it's time to pay more attention to the latter. To shift some of the industry's focus away from finding implementation bugs and toward identifying common design flaws -- "the Achilles' heel" of security engineering -- the IEEE Computer Society has formed the Center for Secure Design (CSD).
The CSD grew out of a foundational workshop, held in April, which brought together software security experts from industry, academia and government to talk about the problem of secure software design. Among the 10 workshop participants were representatives from Twitter, Google, RSA, Intel and Harvard University.
Gary McGraw, CTO of Cigital, hosted a soirée at the Cantina art bar in San Francisco to launch the CSD and to generate interest in its mission. McGraw was among the original workshop members. "The price of admission was a bag of flaws -- a real bag of flaws -- from your practice," McGraw told attendees. "We dumped them all on the table and picked the tallest 10 piles."
That mission, by the way, is to "gather software security expertise from industry, academia and government" to provide guidance on "recognizing software system designs that are likely vulnerable to compromise" and "designing and building software systems with strong, identifiable security properties." And those 10 piles led to the publication of an inaugural CSD report, "Avoiding the Top 10 Software Security Design Flaws."
McGraw, who is author of numerous books about building secure software, called finding and fixing design flaws "the hardest problem that nobody has solved."
"Software security has grown into a $7 or $8 billion industry, and it's continuing to grow very fast," he told me. "But the field seems to be myopically focused on bugs and hackers. And yet, from a technical perspective, half of the problem is a design problem. We're hoping to shepherd the field in the right direction."
The CSD is part of a larger IEEE cybersecurity initiative launched this year "with the aim of expanding its ongoing involvement in cybersecurity." Jim DelGrosso, principal consultant at Cigital, will serve as the CSD's executive director. One of the problems the group will address, DelGrosso said, is the relative opaqueness of the work being done on design flaws.
"We've known about these things for a decade or three," he told attendees, "and yet the problems persist. We also know that this work is being done, but much of it is being done internally, so it's not available to the public. One of the goals of the CSD is to change that. We want people to stop making these mistakes."
Google information engineer Christoph Kern shared an example of such internal work from his own company, where he has been developing Web application frameworks that make it hard for developers to introduce cross-site scripting bugs. One team that adopted the frameworks saw a marked reduction in their bug-tracker stats. "There's a real connection between bugs and design-level considerations," he said.
Here's the list of initial participants in the Center for Secure Design:
- Iván Arce, Sadosky Foundation
- Neil Daswani, Twitter
- Jim DelGrosso, Cigital
- Danny Dhillon, RSA
- Christoph Kern, Google
- Tadayoshi Kohno, University of Washington
- Carl Landwehr, George Washington University
- Gary McGraw, Cigital
- Brook Schoenfield, Intel/McAfee
- Margo Seltzer, Harvard
- Diomidis Spinellis Athens University of Economics and Business
- Izar Tarandach, EMC
- Jacob West, HP
Here are those top 10 security design flaws; each one is fleshed out considerably in the CSD report:
- Earn or give, but never assume, trust
- Use an authentication mechanism that cannot be bypassed or tampered with
- Authorize after you authenticate
- Strictly separate data and control instructions, and never process control instructions received from untrusted sources
- Define an approach that ensures all data are explicitly validated
- Use cryptography correctly
- Identify sensitive data and how they should be handled
- Always consider the users
- Understand how integrating external components changes your attack surface
- Be flexible when considering future changes to objects and actors

There's nothing like seeing the final agenda go up on a Web site to drive home the reality that you're chairing your first technology conference.
Fortunately for me, that agenda -- the one for our first ever App Dev Trends conference coming in December in Las Vegas -- is filled with workshops and sessions led by some of my favorite enterprise software experts, industry mavens, market watchers and serious codederos. I might be as nervous as a nerd at the prom about stepping onstage in my chairing duties (man, that simile brought up some bad memories), but I couldn't be more relaxed about our kick-ass presenter lineup.
I'm very excited, for example, to have David Intersimone (better known as "David I.") speaking at the show. Intersimone is vice president of developer relations and chief evangelist for toolmaker Embarcadero Technologies, and he's a programmer's programmer. He worked for more than two decades at Borland, the company that invented the IDE, then at CodeGear, the company that emerged from Borland's decision to shed its tools business. David will be presenting two sessions: "Integrating Devices and Gadgets into Your Enterprise" and "Clouds: The Final Frontier – Integrating BaaS into your Enterprise Apps."
We also have one of my all-time favorite conference keynoters, Miko Matsumura, leading a session. He's now vice president of developer relations at Hazelcast, the open source in-memory data grid company, but I first saw Miko when he served as chief Java evangelist at Sun Microsystems in the late '90s. (Back when he had shoulder-length hair!) He was one of the most visible spokespeople for Java back then, and a member of the team that popularized the Java platform among developers. In his session, "Elastic Application Performance Market View," Miko will examine the dizzying array of options available today for architecting scalability into applications from Day 1.
When Dr. James McCaffrey, a popular veteran of 1105 Media's Visual Studio Live! conferences and Visual Studio Magazine columnist, responded to my e-mail pestering by saying that he might have a totally new tool to present at our show, and that this tool was designed for developers interested in neural networks, I swallowed my gum! You've probably heard about Microsoft's new cloud-based machine-learning tool, Machine Learning Studio, the beta of which was unveiled in July. His presentation is titled: "Understanding Neural Networks Using Python." McCaffrey, who works at Microsoft Research, promises that attendees will come away from his session with an in-depth understanding of neural networks -- and to include one of the first public demos of the new Machine Learning Studio.
I am also very excited about Ian Skerrett's session, "Introducing Eclipse IoT: Accelerating IoT Development." Over the past two years, the Eclipse Foundation has been developing a community of open source projects for Internet of Things developers. That community now comprises 15 different projects, and includes implementations of popular IoT standards, such as CoAP, MQTT, and Lightweight M2M. Ian is the man who has been leading the effort to build that community. He will be talking about the project itself and how to use the technologies it encompasses to get started building IoT solutions.
One of my favorite tech industry watchers, Theresa Lanowitz, founder of voke inc., is also presenting at our show. Her official bio says that she's widely recognized as "a strategic thinker and influencer in the application life cycle, virtualization, cloud computing, and convergence markets." I usually hate to use PR-speak, but that line is right on the money. Cool tidbit from that bio: She worked on the original JBuilder IDE. I've interviewed Theresa many times, and I'm looking forward to both of her sessions: "Extreme Automation: Software Quality for the Next-Generation Enterprise," and "Software Quality in the Sound Bite Era."
And our own Agile Architect, Dr. Mark Balbes, will be among the speakers kicking off the show with his session, "The State of Agile." Mark will be talking about the evolution of Agile -- what works, what doesn't and where the Agile movement might be heading in the future. He'll also be there to wrap things up with our closing panel, "Agile Techniques and Best Practices," which will feature Mark, Matt Philip and Jason Tice, the Three Agilistos from our popular summer webcast. I'll be moderating this panel, so it'll be worth attending for my embarrassing gaffes alone.
It's no exaggeration to say that this is just the tip of the iceberg. This is our first-ever ADT-branded event, and we went all out to put together what I believe is a killer agenda with sessions focused on the enterprise developer. App Dev Trends 2014 runs Dec. 8-11 at the Mandalay Bay Resort and Casino in Las Vegas. Hope to see you there!

Java toolmaker ZeroTurnaround's software release automation tool, LiveRebel, is a little less live than it was a week ago. The company pulled the plug on the three-year-old sibling of its JRebel JVM plug-in (and newly birthed XRebel Java profiler). Company founder and CEO Jevgeni Kabanov, delivered the news in a blog post, though he says customers were contacted before he posted.
I caught up with Kabanov via Skype in Estonia, where his company is headquartered, to ask him about it. He said there just wasn't enough of a mid-range release management market to sustain the product.
"LiveRebel was aimed at the mid-market," he said. "That's a few dozen up to a couple hundred servers. But most of our competitors were going after customers with hundreds to thousands of servers. We just felt that there was a significant opportunity cost for going after that market."
Another problem, Kabanov said he believes, is that there is no agreement currently on exactly what a "release management" product should do -- especially within the context of a rapidly evolving of DevOps and continuous delivery movements. But perhaps more important, whatever release management is, it doesn't currently seem to be at the top of ZT's customers' to do lists. In his blog post, he put it this way: "Release management provides little value if you don't have automated builds, provisioning, and a well-defined release process, and unfortunately most potential customers would have none of those."
"It was a tough decision emotionally, but from a business perspective, it was quite straight forward," he said. "For now, we're continuing to focus on the developer tools market, which is our strength. But we're not closing any doors on what we might do in the future."
LiveRebel 1.0 was released in May 2011 after about three years of development "in the far northern country of Estonia as an attempt to re-invent product updates." The final version, 3.1, was released last month. Kabanov said active customers would be getting refunds and support and help migrate off LiveRebel until August 2015.
The Tartu, Estonia-based company is probably best known for its JRebel plug-in, which integrates with the Java Virtual Machine (JVM) and app servers on the class loader level, and allows developers to make on-the-fly code changes in Java class files. In June, the company released an interactive Java profiler called XRebel. The company also operates a research and content organization, Rebel Labs, which publishes free, vendor-neutral technical resources.

Enterprise developers struggling with the challenges associated with mobile application development may not be settling on a single, one-size-fits-all tool or platform just yet, but they are approaching those challenges more strategically. That, according to IDC analyst Al Hilwa, writing in a recently published report: "Negotiating the Mobile Disruption: Approaches for Multiplatform Application Development."
Hilwa, who is a research director in IDC's Application Development Software group, told me that he's trying to be the voice of reason in this report, offering "concrete, realistic advice to enterprises."
He first states the obvious, that "the central problem in mobile application development is addressing the variety of platforms and devices that employees can bring into the enterprise in a productive and agile manner…"

How are shifting consumer behaviors, new digital channels, application standards, and open source trends influencing current approaches to customer-facing software development? That's a big, scary question, but the panel of experts assembled to answer that question during Actuate's iHub F-Type launch in San Jose recently weren't intimidated in the least.
In fact, customer strategist Esteban Kolsky, principal and founder of ThinkJar, took issue with the title of the panel -- "Building the Next Big App" -- arguing that the next big app could very well be small.
Posted by John K. Waters on 07/28/2014 at 4:33 PM0 comments
Actuate signed on with the Eclipse Foundation as a Strategic Developer back in 2004, just a few months after the organization was founded. The South San Francisco-based company proposed the industry's first open-source Business Intelligence and Reporting Tools project (BIRT), and a decade later, BIRT is one of the best known open-source initiatives for data-driven development.
Now, the company says it's entering a "new chapter" with the launch of a freemium version of its iHub data visualization platform.
The BIRT iHub platform integrates and manages BIRT Analytics apps and BIRT-based information. It converts that information into graphs, charts, tables and diagrams, and more. The new BIRT iHub F-Type is designed to manage and distribute content created with both the open-source BIRT and the company's commercial BIRT Designer Pro IDE. It gives developers free access to the features of the commercial BIRT iHub platform with "metered output capacity." In other words -- or rather, in the words of Actuate CEO Pete Cittadini, "Actuate is now a subscription business."
"We've seen IT shifting to the so-called subscription economy for several years now," Mike Milinkovich, executive director of the Eclipse Foundation, told ADTmag. "It's becoming an increasingly common way to sell software. But this is still a big move for the company."
In Actuate's version of this model, the volume of daily data output is limited to a level "suitable for many developers' needs" (50MB), but there's no limit on data input. When the daily output exceeds 50MB, they can buy additional capacity from within iHub F-type. And the company is allowing devs to exceed that daily limit twice in a month before hitting them with a charge.
"We're targeting Eclipse BIRT developers, of course, but non-BIRT Java developers, too" said Nobby Akiha, Actuate's senior vice president of marketing. "And a big focus has been on the user experience. You'll be up and running in 15 minutes. "
Actuate's move to a subscription model is probably a smart one for the company, says Redmonk analyst Stephen O'Grady, and good news for developers. "They're giving developers a chance to leverage these capabilities in a way that makes it easy for them to do it," he said. "Availability and ease of access are overlooked surprisingly often by commercial software organizations. You can have the best solution in the world, but if it's hard for me to get, and there's something that's even half as good, frankly, that I can get easily, I'm going to do that. We see this over and over again."

Typesafe this month marked the five-year anniversary of Akka, its open-source run-time toolkit for concurrency and scalability on the Java Virtual Machine (JVM).
Written in Scala and used to build highly scalable, fault-tolerant applications in both Scala and Java, Akka has gained serious traction since Swedish programmer Jonas Bonér pushed out the first public release (v.05) on July 12th, 2009. The company now includes some big names on its Akka user list, including Amazon, BBC, Cisco, Credit Suisse, eBay and more.
Bonér, who is Typesafe's CTO and co-founder, had worked for years building compilers, runtimes, and open source frameworks for distributed apps. Somewhere along the way, he says, he became "fed up" with the scale and resilience limitations of CORBA, RPC, XA, EJBs, SOA, and the Web Services standards and abstraction techniques Java developers typically used.
"It started to dawn on me that it wasn't that we were using the wrong tools," Bonér told ADTmag. "It was a fundamentally wrong approach to building software."
A better approach, Bonér concluded after "tinkering" with the Oz and Erlang languages, was the Actor Model, which utilizes objects that encapsulate state and behavior. Each actor also has a mailbox, and communicates exclusively by exchanging messages placed into a recipient's mailbox. This model provides a unified, single abstraction over concurrency and distributed computing. And an Actor's behavior can be redefined at runtime.
"I found the Actor Model to be a really good basis for building this next generation middleware," Bonér said. "And I could see that we needed to bring them over to the JVM."
Akka is one of the technologies emerging around the concept of reactive applications, described in "The Reactive Manifesto" as apps that better meet the "contemporary challenges of software development," in a world in which applications are deployed to everything from mobile devices to cloud-based clusters running thousands of multicore processors. Bonér wrote the first version of manifesto, which defines the four "critical traits" of reactive apps: event-driven, scalable, resilient, and responsive. By embracing these traits, the manifesto asserts, developers produce apps that are highly responsive to user experiences, provide a real-time feel, and are backed by a "scalable and resilient application stack" that can be deployed just about anywhere. A number of others contributed to later drafts of that manifesto, including Typesafe's other co-founder, Martin Odersky, who created the Scala language. That list of contributors also includes Erik Meijer, Greg Young, Martin Thompson, Roland Kuhn, James Ward, and Guillaume Bort. Since it was published, hundreds have "signed" the manifesto.
Odersky created Scala, a general purpose, multi-paradigm language that runs on the JVM, to integrate features of object-oriented programming and functional programming. Typesafe is also responsible for the Play Web app framework, a development and runtime environment billed as "a clean alternative to legacy Enterprise Java stacks." Play compiles Java and Scala sources directly and "hot reloads" them into the JVM.
In 2013 Typesafe acquired of Spray.io, a suite of lightweight Scala libraries that provide client- and server-side REST/HTTP support on top of Akka. The company hoped to broaden the appeal of the Typesafe Platform to Java developers with "one of the best performing REST/HTTP libraries in the Java ecosystem," Boner said.
The Akka team, which now comprises six members ("It's a good size," Boner said), shipped version 2.2 in July 2013. That release included full support for clustering. In October of that year, the team introduced Akka Persistence to allow stateful actors to recover from JVM crashes "in a way that Actors themselves are persisted in memory," the company explained. In April 2014, Typesafe unveiled early preview releases of two projects designed to improve data streaming on the JVM: Akka Streams and Reactive Streams (ADTmag coverage here).
Typesafe has posted an infographic of the history of Akka that shows its evolution, the influence of Scala Actors on its development, the Oz/Erlang connection, the emergence of the Akka Persistence module, and all the creative people involved—not to mention how it got its name. (Hint: It's not an acronym.)

The annual Google I/O developer conference, which wrapped up this week in San Francisco, packed its usual punch with a number of announcements and free stuff for attendees.
We saw the first example of Android Wear software for wearable devices, coming initially in LG's G Watch and Samsung's Gear Live, and later in Motorola's Moto 360. We saw Android TV, which Google will make available to new television sets from vendors like Sony and Sharp.
There was no mention of Google+ in the keynote; make of that what you -- and everybody else -- surely will. There wasn't much talk about Google Glass, either. No skydiver. And no Larry Page on the keynote stage.
In his mobile-focused keynote, Sundar Pichai, Google's SVP of Android, Chrome, and Apps, announced Android One, a new initiative that provides low-end hardware and software to emerging mobile markets, such as his home country of India. And he unveiled the new Android for Work initiative, which will partition personal and work apps on Android and Chrome for added security. (Look for Android at Work in the upcoming Android L operating system update.) And the new Android Auto.
Pichai also dropped some mad stats: a billion "30-day active" users (currently active) of the Android Platform, who send 20 billion test messages and take 93 million selfies per day. Android tablets now account for 62 percent of the global market, and app installs on the tablet is up 236 percent. He also mentioned that this year's conference is made up of 20 percent women, up from just 8 percent last year. Not sure what that means, either, but that's quite a year-to-year jump.
But the big news for developers at this year's show: 5,000 new APIs that will connect Android devices to a broad set of services on the Net and on other devices. Google also released the Android SDK for devs building apps for wearable computing.
IDC analyst Al Hilwa called the Google announcements "an amazing buffet of capabilities and APIs for developers that truly expands the Google ecosystem."
"The reach of the platform to wear, auto, home and TV, as well as connecting them together, really begins to show the connectedness of Android as the leading mobile platform," Hilwa told me. "What came across [in the keynotes] is the expansiveness of the platform overall. I did get a sense at the keynote that Google is talking to the whole world not just to a premium club. Does this mark a transition of the mobile leadership from Apple to Google? We will find out for sure when Apple makes its late fall announcements."
Google highlighted four new Cloud Platform tools for developers:
- A new version of Cloud Save, a service that enables non-relational, per-user data to be storage and synced in apps with no backend programming required.
- Google Cloud Monitoring, which uses technology from the company's recent Stackdriver acquisition to provide dashboards and alerting capabilities for finding and fixing performance problems.
- Cloud Debugger Monitoring, which changes the standard debugging model by allowing developers of cloud-based apps to set "watchpoints" on lines of code, which gives them "a snapshot of all the local variables, parameters, instance variables and a full stack trace," Google says.
- Cloud Trace Monitoring, a performance tool designed to give developers the ability to "visualize and understand the time spent by your application for request processing," and thus pinpoint bottlenecks.
"For developers there's a lot to play with here," Hilwa added. "APIs at every level will enable a new generation of apps connecting smartphones to other objects in life .... It will take some time for developers to absorb all the new APIs, but we will begin to see the impact of these announcements in the coming year. I expect that new SDK's will be added over time to cover other realms of the IoT world."
